The main reason why American mutual fund is so advanced is that there is the concerted mechanism environment for mutual fund, such as the mature financial market, sufficient investment capital supply, well-developed system of laws and so on. Adopting the specific exponents of Shanghai and Shenzhen Security Market, fund exponent yields, all weekly yields of mutual fund in specific periods, etc., the positive analysis of the coordination of Chinese mutual fund and Security Market demonstrates that this coordination is not ideal generally. On condition that the market characteristic of mutual fund is made clear, mutual fund can develop conceitedly and healthily by developing security market, increasing market efficiency, providing more fund, improving fund management, standardizing relative system of privately offered funds and so on, and optimizing the market environment to develop mutual fund.

美国开放式基金之所以发达，主要原因在于开放式基金具有协调发展的制度环境，如成熟的金融市场、充足的投资资金供给、完善的法律体系等；采用沪、深证券市场特定指数与基金指数收益率，及特定时期内所有开放式基金的周收益率等指标，对我国开放式基金与证券市场的协调性的实证分析发现，二者协调性程度总体上不理想；在明确开放式基金发展的市场过程性质的前提下，通过促进证券市场的成熟、提高市场效率、完善法律、拓宽基金资金供应渠道、完善基金治理结构、规范私募基金发展等配套措施，优化开放式基金发展的市场环境，才能不断促进开放式基金的协调、健康发展。

In the single crystal of C60 with a FCC structure,positron mainly appears outside the C60 molecule.The main annihilation space is the interspace between molecules.The calculated positron bulk lifetime in C60 is 352ps, which agrees with experiment value of 356ps in literature.In carbon nanotube bundles with different dimeters,as the diameter of carbon nanotubes increases,the main space where positron appears changes from the interspace of carbon tubes to the space inside carbon tubes,the radio between positron annihilation with valence eletrons and core eletrons becomes larger,the positron bulk lifetime in carbon nanotube increase rapidly first and come to be a constant at the end.The calculated positron lifetime of carbon nanotube with a dimeter of 0.8～1.6ns is 332～470ps,which agrees with the experiment value of 394ps.Positron annihilation has been studied in widly used compound semiconductors.

计算结果表明：在片层结构的石墨晶体中，正电子主要在石墨层间的空隙中湮没，计算出的石墨中的正电子寿命为208 pS，与文献中的实验结果215 ps符合很好；在金刚石单晶中，正电子主要在碳原子之间的空隙中存在并发生湮没，计算出的金刚石中的正电子寿命为115 ps，文献中的实验结果110 ps左右符合；在面心立方结构的C60晶体中，正电子主要在C60分子球壳内外侧及分子之间存在，C60球形分子中心正电子分布很少，正电子的湮没区域集中在C60分子之间的空隙区域，计算出的C60中的正电子寿命为352 ps与文献中的实验结果356ps相符合；对于不同管径碳米管束中的正电子分布，随着碳纳米管直径的增加，碳纳米管束中的正电子由主要在碳纳米管管间的区域出现转变为主要在碳纳米管管内中心的区域出现：碳纳米管束中的正电子与碳原子的价电子的湮没概率变得越来越大，与核心电子的湮没概率变得越来越小；碳纳米管束中正电子的湮没寿命先迅速增大，而后趋于一定值。

Following the dual principle of the circuit theories,the dual network of mutual inductance network ,the concept of mutual capacitance,and the dual relation of mutual capacitance and mutual indutance are analysed and substantiated,and the decoupling equivalent circuit of mutual capacitance is discussed as well.

从电路理论对偶原理出发，分析论证了互感网络的对偶网路、互电容的概念及互电容与互电感的对偶关系，并探讨了互电容的去耦等效电路。
